Wholegrain

BNF said: “Fibre doesn’t tend to get much attention, often only associated with ‘keeping you regular’, but it’s actually important for many health outcomes including heart disease, type 2 diabetes and colon cancer.

“Whilst we are frequently being encouraged to reduce our portion sizes, the daily fibre recommendation has actually recently been increased to 30g per adult per day.

“But, on average UK adults are only getting about 18g per day, meaning we’re well below recommendations.”

Fruit and vegetables

Green vegetables provide us with important micronutrients, including calcium, iron, vitamin A, folate and vitamin C.

Leafy greens could improve your metabolism and keep you hydrated for longer.

BNF said: “Rocket, watercress, kale, spinach, Brussels sprouts, okra and broccoli are all examples of nutrient-rich green vegetables so make sure they’re part of your five-a-day.

“For those of us who enjoy the sweeter side of life, eating more fruit is a healthy (and delicious) way to kick the sugar cravings and fill the void left by the mince pies, puddings and Christmas chocolates.”
